Yes I know that touchscreens on TouchPro2 and like phones dont support multi-touch well. I hope that future phones and ROMs support it better. Yes it took me a couple of weeks to make all the levels and the final boss fight with bowser. After all the hard work the game came off just the way I wanted it.
Ok so you played the game and at some points its pretty tough. Here some tips and tricks to help you out.
1) When you jump but just miss but hit the side of a plateform press forward button and mario can climb up the side of the plateform.
2)Some coins in the game are unreachable, its a trap so dont try to collect every coin in every stage.
3) When you fight final boss bowser stay on left side of screen. You see a platform in the middle of screen moving up and down. You faintly see a turtle in the background and when the moving platform hits the turtle a shell appears. Hit the turtle shell and it hit boswer. Boswer has about 20 hit points so it will be a long fight.
4)When you die its better to use stylus to press start to restart level.
Enjoy the game and have fun if you need any help tell me here or PM me.
